It's the prize no author wants to win. Award-winning novelist Nancy Huston has won Britain's Bad Sex in Fiction award for her novel Infrared, whose tale of a photographer who takes pictures of her lovers during sex proved too revealing for the judges.

The choice was announced by Downton Abbey actress Samantha Bond during a ceremony at the Naval & Military Club in London.

Judges of the tongue-in-cheek prize - which is run by the Literary Review magazine - said they were struck by a description of ''flesh, that archaic kingdom that brings forth tears and terrors, nightmares, babies and bedazzlements,'' and by a long passage that builds to a climax of ''undulating space.''

Huston, who lives in Paris, was not on hand to collect her prize. In a statement read by her publicist, the 59-year-old author said she hoped her victory would ''incite thousands of British women to take close-up photos of their lovers' bodies in all states of array and disarray.''

The Canada-born Huston, who writes in both French and English, is the author of more than a dozen novels, including Plainsong and Fault Lines.

She has previously won France's Prix Goncourt prize and was a finalist for Britain's Orange Prize for fiction by women. She is only the third woman to win the annual Bad Sex prize, founded in 1993 to name and shame authors of ''crude, tasteless and ... redundant passages of sexual description in contemporary novels.''

Some critics, however, have praised the sexual passages in Infrared.

Shirley Whiteside in the Independent on Sunday newspaper said there were ''none of the lazy cliches of pornography or the purple prose of modern romantic fiction'' - though she conceded the book's sex scenes were ''more perfunctory than erotic.''

Previous recipients of the dubious honor, usually accepted with good grace, include Sebastian Faulks, the late Norman Mailer and the late John Updike, who was awarded a Bad Sex lifetime achievement award in 2008.
